Performance Air Intake For Ford Explorer/Ranger (1991-1994) with 4.0L OHV V6 Engine Blue

Give your first-gen Explorer or Ranger the breath of fresh air it deserves and finally fix that sluggish throttle response common to the aging 4.0L OHV Cologne V6.

Performance Air Intake Upgrade for Ford Explorer & Ranger (4.0L OHV V6)

If you’re still running the original factory air box on your 1991-1994 Ford, you’re essentially forcing your engine to breathe through a straw. The stock plastic housing was designed more for sound dampening than flow, often becoming brittle and prone to vacuum leaks over decades of heat cycles. This performance intake replaces that restrictive, heat-soaked factory assembly with high-flow T304 lightweight aluminum piping finished in a stealthy black coating.

The 4.0L OHV V6 is a legendary "tractor" motor—reliable and torquey, but it lacks top-end efficiency. By streamlining the air path to the manifold, this kit reduces pumping losses and allows the engine to reach its power band more effectively. Whether you are navigating a trail or merging onto the highway, the improvement in throttle response is immediate. Plus, you’ll get that signature deep, throaty growl under load that the factory silencers were designed to hide.

This kit isn't just a performance mod; it’s a smart maintenance move. The included high-flow filter is fully washable and reusable, meaning you can stop hunting for paper filters at the parts store. It’s a simple, bolt-on solution that modernizes your intake tract without requiring any permanent modifications to your classic Ford chassis.

Why You Need This Upgrade

• Optimized Power Delivery: Potential gains of up to 10% in horsepower and torque by maximizing airflow to the stock manifold.
• Stealth Durability: Features T304 aluminum piping with a rugged black coating that resists corrosion and looks professional under the hood.
• Enhanced Intake Sound: Replaces the muffled factory tone with a deep, sporty engine note during acceleration.
• Lifetime Filtration: Includes a washable, reusable filter that only requires service every 50,000 miles in normal conditions.
• Efficient Combustion: Improved airflow helps the engine breathe easier, leading to better throttle response and more efficient fuel mapping.

Installation Notes

Installation is straightforward and can be completed in your driveway with basic hand tools like a socket wrench and screwdriver. The kit is a direct replacement for the factory air box and intake tube. Critical Step: You must disconnect your battery terminal during the install. This allows the engine computer to reset and "re-learn" the new airflow parameters once you fire it back up, ensuring optimal fuel-to-air ratios from the first drive.
